This is a list of dinosaurs whose remains have been recovered from Australia or Antarctica.
Name | Year | Formation | Location | Notes | Images |
---|---|---|---|---|---|
Antarctopelta | 2006 | Snow Hill Island Formation (Late Cretaceous, Maastrichtian) | Antarctica | Possessed unusual caudal vertebrae that may have supported a "macuahuitl" as in Stegouros [1] | |
Atlascopcosaurus | 1989 | Eumeralla Formation (Early Cretaceous, Aptian to Albian) | Australia | Only known from remains of jaws and teeth | |
Australotitan | 2021 | Winton Formation (Late Cretaceous, Cenomanian to Turonian) | Australia | The largest dinosaur known from Australia, comparable in size to large South American dinosaurs. Potentially a synonym of the contemporary Diamantinasaurus [2] | |
Australovenator | 2009 | Winton Formation (Late Cretaceous, Cenomanian) | Australia | Analysis of its arms suggests it was well-adapted to grasping [3] | |
Austrosaurus | 1933 | Allaru Formation (Early Cretaceous, Albian) | Australia | Its holotype was found associated with marine shells | |
Cryolophosaurus | 1994 | Hanson Formation (Early Jurassic, Pliensbachian) | Antarctica | Had a distinctive "pompadour" crest that spanned the head from side to side | |
Diamantinasaurus | 2009 | Winton Formation (Late Cretaceous, Cenomanian) | Australia | May have been closely related to South American titanosaurs, suggesting they dispersed to Australia via Antarctica [4] | |
Diluvicursor | 2018 | Eumeralla Formation (Early Cretaceous, Albian) | Australia | Lived in a prehistoric floodplain close to a high energy river | |
Fostoria | 2019 | Griman Creek Formation (Late Cretaceous, Cenomanian) | Australia | Four individuals have been found in association | |

Glacialisaurus | 2007 | Hanson Formation (Early Jurassic, Pliensbachian) | Antarctica | Basal yet survived late enough to coexist with true sauropods [6] | |
Imperobator | 2019 | Snow Hill Island Formation (Late Cretaceous, Maastrichtian) | Antarctica | Initially described as a basal paravian although it may potentially be an unenlagiine [7] | |

This is a timeline of selected dinosaurs from the list above. Time is measured in Ma, megaannum, along the x-axis.
Fukuiraptor was a medium-sized megaraptoran theropod dinosaur of the Early Cretaceous epoch that lived in what is now Japan. Fukuiraptor is known from the Kitadani Formation and possibly also the Sebayashi Formation.
The Huincul Formation is a geologic formation of Late Cretaceous age of the Neuquén Basin that outcrops in the Mendoza, Río Negro and Neuquén Provinces of northern Patagonia, Argentina. It is the second formation in the Río Limay Subgroup, the oldest subgroup within the Neuquén Group. Formerly that subgroup was treated as a formation, and the Huincul Formation was known as the Huincul Member.
The Portezuelo Formation is a geologic formation of Late Cretaceous age, outcropping in the Mendoza, Río Negro and Neuquén provinces of Argentina. It is the fourth-oldest formation in the Neuquén Group and the older of the two formations in the Río Neuquén Subgroup. Formerly, that subgroup was treated as a formation, and the Portezuelo Formation was known as the Portezuelo Member.
The Winton Formation is a Cretaceous geological formation in central-western Queensland, Australia. It is late Albian to early Turonian in age. The formation blankets large areas of central-western Queensland. It consists of sedimentary rocks such as sandstone, siltstone and claystone. The sediments that make up these rocks represent the remnants of the river plains that filled the basin left by the Eromanga Sea - an inland sea that covered large parts of Queensland and central Australia at least four times during the Early Cretaceous period. Great meandering rivers, forest pools and swamps, creeks, lakes and coastal estuaries all left behind different types of sediment.
Macrogryphosaurus is a genus of elasmarian dinosaur from the Coniacian age Upper Cretaceous Sierra Barrosa Formation of Argentina in Patagonia. It was described by Jorge Calvo and colleagues in 2007, with M. gondwanicus as the type and only species.
The Eumeralla Formation is a geological formation in Victoria, Australia whose strata date back to the Early Cretaceous. It is Aptian to Albian in age. Dinosaur remains are among the fossils that have been recovered from the formation, particularly from the Dinosaur Cove locality.
Australovenator is a genus of megaraptoran theropod dinosaur from Cenomanian -age Winton Formation of Australia. Some specimens from the Albian-aged Eumeralla Formation as well as the Wonthaggi Formation may belong to Australovenator. It is known from partial cranial and postcranial remains which were described in 2009 by Scott Hocknull and colleagues, although additional descriptions and analyses continue to be published. It is the most complete predatory dinosaur discovered in Australia. It has been suggested that Australovenator is a sister taxon to Fukuiraptor, although some phylogenetic analyses find it to be a more derived member of the Megaraptora, possibly being part of the main Megaraptoridae family itself.
Wintonotitan is a genus of titanosauriform dinosaur from Cenomanian -age Winton Formation of Australia. It is known from partial postcranial remains.
Elasmaria is a clade of ornithopods known from Cretaceous deposits in South America, Antarctica, and Australia that contains many bipedal ornithopods that were previously considered "hypsilophodonts".
Trinisaura is a genus of ornithopod dinosaur that lived during the late Campanian stage of the Upper Cretaceous, around 73 to 72 million years ago in what is now James Ross Island off the coast of northern Antarctica near Patagonia. It is known from a single, incomplete postcranial skeleton that includes several vertebrae, a partial pelvis, and nearly complete right hindlimb. The fossils were collected in 2008 by paleontologists Juan Moly and Rodolfo Coria from the sandstone of the Snow Hill Island Formation. It remained undescribed in the collections of the Museo de La Plata until its description by Coria and colleagues in 2013, being the basis of the novel genus and species Trinisaura santamartaensis. The genus name is to commemorate the efforts of Argentine geologist Trinidad "Trini" Diaz and the Latin root -sauros, meaning "lizard". The species name is after Santa Marta Cove, where the fossils were collected.
Morrosaurus is an extinct genus of herbivorous elasmarian dinosaur that lived in the late Cretaceous in Antarctica. The only known species is the type Morrosaurus antarcticus.
Savannasaurus is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Winton Formation of Queensland, Australia. It contains one species, Savannasaurus elliottorum, named in 2016 by Stephen Poropat and colleagues. The holotype and only known specimen, originally nicknamed "Wade", is the most complete specimen of an Australian sauropod, and is held at the Australian Age of Dinosaurs museum. Dinosaurs known from contemporary rocks include its close relative Diamantinasaurus and the theropod Australovenator; associated teeth suggest that Australovenator may have fed on the holotype specimen.
The Sierra Barrosa Formation is a geologic formation of the Neuquén Basin in the northern Patagonian provinces of Mendoza and Neuquén. The formation dates to the Late Cretaceous, middle to late Coniacian, and belongs to the Río Neuquén Subgroup of the Neuquén Group. The formation overlies the Los Bastos Formation and is overlain by the Plottier Formation. As the underlying Los Bastos Formation, the Sierra Barrosa Formation comprises mudstones and sandstones deposited in a fluvial environment.
Diamantinasauria is an extinct clade of somphospondylan titanosauriform sauropod dinosaurs with close affinities to the Titanosauria, known from the early Late Cretaceous (Cenomanian-Turonian) of South America and Australia. It was named by Poropat and colleagues in 2021, and contains four genera: Australotitan, Savannasaurus and Diamantinasaurus from the Winton Formation of Queensland, as well as Sarmientosaurus from the Bajo Barreal Formation of Patagonia. The existence of the clade indicates connectivity between Australia and South America via Antarctica during the Cretaceous period.
Maip is a genus of large megaraptorid theropod dinosaur from the Late Cretaceous (Maastrichtian) Chorrillo Formation of Santa Cruz, Argentina. The genus contains a single species, M. macrothorax, known from an incomplete, disarticulated skeleton. Maip may represent the largest megaraptorid known from South America, and possibly the world.
Chakisaurus is an extinct genus of elasmarian ornithopod dinosaur from the Late Cretaceous Huincul Formation of Argentina. The genus contains a single species, C. nekul, known from multiple partial skeletons belonging to individuals of different ages. Chakisaurus represents the first ornithischian species to be named from the Huincul Formation.
